【问题描述】：

我设置了一个基本的 springboot 应用程序，它将在 get 调用时返回字符串值，但是当我尝试返回一个模拟 Patient 对象时，我得到一个奇怪的错误

我的代码：

@RequestMapping("/test2")
Patient test2()
    Patient patient = new Patient();
    patient.setId("1");
    patient.addName().setFamily("Bar").addGiven("Foo").addGiven("M");
    patient.addAddress().addLine("Address Line 1");
    patient.addAddress().setCity("City Name");
    patient.addAddress().setCountry("Country Name");
    patient.addTelecom().setValue("555-555-1111");

    return patient;

错误似乎是创建的json是递归的并且永无止境。响应的 sn-p 是：

"formatCommentsPre":[],"formatCommentsPost":[],"id":"1","meta":"formatCommentsPre":[],"formatCommentsPost":[],"id":null,"extension":[],"versionId":null,"lastUpdated":null,"profile":[],"security":[],"tag":[],"empty":true,"tagFirstRep":"formatCommentsPre":[],"formatCommentsPost":[],"id":null,"extension":[],"system":null,"version":null,"code":null,"display":null,"userSelected":false,"empty":true,"displayElement":"formatCommentsPre":[],"formatCommentsPost":[],"id":null,"extension":[],"valueNotNull":"","primitive":true,"empty":true,"value":null,"valueAsString":null,"idElement":"formatCommentsPre":[],"formatCommentsPost":[],"id":null,"extension":[],"valueNotNull":"","primitive":true,"empty":true,"value":null,"valueAsString":null,"idElement":"formatCommentsPre":[],"formatCommentsPost":[],"id":null,"extension":[],"valueNotNull":"","primitive":true,"empty":true,"value":null,"valueAsString":null,"idElement":"formatCommentsPre":[],"formatCommentsPost":[],"id":null,"extension":[],"valueNotNull":"","primitive":true,"empty":true,"value":null,"valueAsString":null,"idElement":"formatCommentsPre":[],"formatCommentsPost":[],"id":null,"extension":[],"valueNotNull":"","primitive":true,"empty":true,"value":null,"valueAsString":null,"idElement":"formatCommentsPre":[],"formatCommentsPost":[],"id":null,"extension":[],"valueNotNull":"","primitive":true,"empty":true,"value":null,"valueAsString":null,"idElement":"formatCommentsPre":[],"formatCommentsPost":[],"id":null,"extension":[],"valueNotNull":"","primitive":true,"empty":true,"value":null,"valueAsString":null,"idElement":"formatCommentsPre":[],"formatCommentsPost":[],"id":null,"extension":[],"valueNotNull":"","primitive":true,"empty":true,"value":null,"valueAsString":null,"idElement":"formatCommentsPre":[],"formatCommentsPost":[],"id":null,"extension":

是否有人知道我做错了什么以及为患者发送 FHIR 响应的正确方法是什么？

【参考方案1】：

您应该使用 FHIR Parser 将您的对象转换为 JSON，然后将 JSON 值作为简单字符串返回。

// Create a FHIR context
FhirContext ctx = FhirContext.forR4();

// Create a Patient resource to serialize
Patient patient = new Patient();
patient.addName().setFamily("Simpson").addGiven("James");

// Instantiate a new JSON parser
IParser parser = ctx.newJsonParser();

// Serialize it
String serialized = parser.encodeResourceToString(patient);

// Return the result
return new ResponseEntity<>(serialized, HttpStatus.OK);
